RULlNG-MACHINE..

SPECIFICATION forming part of Letters Patent No. 316,990, dated May 5, 1885.

Application filed March 17, 1884.

To all whom it may concern.-

Be it known that we, MARTIN L. METZGER and ALBERT COOPER, citizens of the United States, residing at Harrisburg, in the county of Dauphin and State of Pennsylvania, have invented new and useful Improvements in RulingM-achines, of which the followingisa specification.

This invention relates to certain new and useful improvements in ruling-machines; and it has for,its objects, first, to provide means whereby paper may be so regulatedin passing through the machine that the successive sheets shall lap or immediately succeed each other, so that each succeeding sheet shall pass under the pens just as thelines of the preceding sheet are finished,whether they extend over a whole or a portion only of that sheet, and this in order to present unruled paper to the pens without having a gap appear between the successive sheets, and consequently cause'the pens to run over and saturate the apron or make it necessary to elevate them to ride over such gaps, either of which entails loss of workingtime of the machine; second, to provide means whereby the machine shall be capable of ruling a given number of lines of apredetermined length simultaneously with the ruling of two or more other lines varying in length from those whose measurement is predetermined, and also varying with respect to each other; third, to combine a variable-power transmit ter with a cam-head on the pen-cylinder shaft for actuating the pen-beam carrying the nest of pens; fourth, to combine such power-transmitter with cams for actuating the stop-gate a predetermined intervals, whereby the suction of one of the side beams broken away;

The letter A designates the frameupon which our improved machine is mounted, the same being constructed of wood and of the ordinary type. At the head of the machine are mounted in suitable bearings the feeding and apron rollers B and O, the former being provided with a series of peripheral grooves, in which the usual guide-cords are designed to ru n. These rollers are provided at one end with gear-wheels D and E, which intergear with each other, and the upper of which receives motion from a drive-pulley mounted on its shaft substituted for the crank shown. By

this means, it will be observed, rotary motion is imparted to the feeding and apron rollers in opposite directions, whereby the paper is drawn into the machine. A shaft,G,ismounted on the upper portion of the metallic frame, to be hereinafter mentioned, and is provided with a gear, F, which meshes with the gear D, whereby motion is imparted to the powertransmitter, as will presently appear.

The letter H indicates the apron, upon which the paper rides through the machine, and which in the present instance passes around the pen-cylinder I, mounted rigidly upon the transverse shaft'J, which has its bearings at either side of the frame. The motion of the apron is in the direction of the arrow, (see Fig. 3,) and by reason of frictional contact with the pen-cylinder I causes the same to re rate with it. This apron in practice usually extends to and around a supporting-roller mounted in bearings at the tail of the machine, but which is unnecessary to be shown, as it forms no part of our invention.

In order to adjust the apron H to the proper tension,we provide the depending brackets K, secured at a convenient point to the side of the frame, and provided with a slot in which fits a journal-block, L. This block receives the journal of the tension-roller M, and is adj usted up and down, as circumstances may require, by means of the set-screw N.

In order to prevent the apron from sagging, and to support the same at or near the stopgate, we further provide a roller, 0, mounted in short arms extending from sliding blocks 1?, which fit within ways Q, secured to the inner face of the side pieces of the frame, and provided with set-screws It, whereby the altitude of said supporting-roller is adjusted.

The letter S indicates a metallic frame bolted to one of the side pieces of the frame, in the upper portion of which, as before observed, is journaled a driving-shaft, G. This shaft is provided at the inner end with a gear-wheel, T, which meshes with an idlerpinion, U, mounted on a stud extending from the arm S pivoted at one end on an extension, S, of the said upper portion of the frame, and supported at the other, as will presently appear. This pinion meshes with a gear-wheel, V, rigidly keyed to a sleeve, W", to which is also rigidly keyed the disk A, the disk and gear being, however, connected together by screws, and on which is mounted an associated disk, A, the key B extending into a key-seat in this disk, whereby the same is capable of movement thereon in the direction of the axis of the sleeve, but is made to move positively with the sleeve in a rotary direction. The sleeve WV is mounted for the greater portion of its length within the tubular extension 0 of the arm S. A bracket, D, is secured firmly at one end to the upper portion of the arm S, and is provided with an aperture near the lower end, which receives the hub .of the disk A, whereby said disk and that end of the sleeve \V are given support. To the hub is secured, preferably by means of screws, an internally-threaded block, E.

In order to adjust the disks A and A to and from each other, by sliding the movable disk A to and fro on the sleeve IV we provide a binding-rod, E, which passes through said sleeve and block E, the block being screwthreaded, to correspond with the threads on the rod. At one end this rod is provided with a hand-wheel, G, whereby it is actuated, and at the other with ahand jam-nut, H, whereby the same is locked in relation to the block E. In order, however, "to allow of the disks A and A accommodating themselves to any slight unevenness between their inner faces and the exterior surfaces of the disk, to be presently described, we interpose between the sleeve NV and hand-wheel G a washer and spiral spring, I.

Extending from the frame S is a short stout shaft, J, upon which are mounted the disk K and the cams L and M, the two cams being rigidly connected together, and also to the said disk, so that they will rotate synchronously. The periphery of this disk is provided with gear-teeth, and the opposite faces of the same near the periphery are beveled off in lines which converge as they extend outwardly, as more clearly represented in Fig. 10. These beveled surfaces are designed to be quite narrow, measuring them in a radial direction. and the inner oropposite faces of the disks A and A are also beveled in diverging lines from their center outward, the bevel of the respective upper disks agreeing in direction with the narrow bevel-surfaces of the lower disk with which they respectively come in contact. By this means we have ascertained that the upper disks can be so firmly impinged against the lower disk as to cause the latter to rotate positively when the'former are rotated, and that with entire smoothness and regularity.

It will appear from what has been said that the upper disks receive rotary motion through the gears V and T and the pinion U; but in order to vary the speed which these disks transmit to the disk K, and those devices which receive motion from it, it is necessary to adjust the upper disks in a radial direction, so as to bring the point of contact between them and the lower disk at different distances from their center. This is done by providing the frame S with an upwardly-extending portion, S, having a slot, N, formed therein in the are of a circle, using the axis of the driving-shaft G as the center therefor. The collar 0 is fitted around the tubular extension 0 of the arm S, and is formed to snugly fit the slot N. To this collar is pivot-ally connected a screw-threaded rod, 1?, to the upper end of which is fitted an internally-screw-threaded hand-wheel, Q, journaled in the upper end of the extension S of the frame S. By this means it will be observed that the upper disks may-be adjusted to and from the center of the lower disk, and the speed imparted to the lower accordingly varied without a variance in the speed of the upper. To maintain these disks in any given position, a washer, R, and a jam-nut, T, are fitted over the extension 0, the latter engaging threads thereon, whereby the arm S is drawn firmly against the extension S, and the center of rotation of the upper disks fixed. Now, in order to predetermine the speed at which the lower disk shall be driven, and the relative speed of the other devices which are primarily actuated through said lower disk, we provide a pointer, U, connecting it with the arm S, and a graduated scale, V, mounted stationarily upon a fixed object, in the present instance upon the extension S of the frame S.

The lines on this scale in the present instance are consecutively numbered 12 to 20, incluthe side pieces of the framein suitable bearings, and is provided with gear-wheels V and W, the former of which meshes with the said disk K, and receives rotary motion therefrom, while the latter of these gears, W, meshes with an idler, X, mounted so as to rotate on a short shaft, Y, having its bearings in a vertically-slotted bracket, Z, secured to the lower edge of one of the side pieces of the frame. This idler in turn meshes with a gear-wheel, a, loosely mounted upon the pen cylinder shaft J, whereby a cam-head, Z), is given rotary motion through the instrumentality of the power-transmitter or disks K, A, and A.

To the gear-wheel a is rigidly connected the cam-head b, the same being also loosely mounted on the shaft J, and being provided with a convenient number of annular recesses and binding-screws, c, to receive and secure the cam-blocks (Z, which serve to actuate the penbeam, to be presently described. This beam consists, preferably, of a strip of wood e, provided at one end with a metallic spindle, f, which extends through a block, g, forming part of a vertically-adjustable slide, h, mounted on ways 1', formed on the standard j. The foot k of this standard fits in ways formed in the stationary plate Z, and is held in a fixed position by a set-screw, m. By this means it will be observed the position of the pen-beam 0 may be adjusted up and down and in a forward or backward direction at the end of said beam, just described.

The standard j and plate Z, as also the setscrew m, are duplicated on the opposite side of the machine, as more clearly represented in Fig. 1, and the upper end of the standard is provided with depending ways 02, within which fits the vertically-adj ustable block 0, a set-screw, 0, having a head and jam-nut, 0", serving to adjust it up and down. This block is internally screw-threaded and receives the correspondingly-threaded spindle 19, having a.

head and jam-nut, q.

The adjacent end of the pen-beam is provided with the plate r, having lugs s. A bar, a, is pivoted within the lugs s, as seen in Fig.

1, and the spindle 1) passes through an apervents it from slipping too far through the block. By this means the pen-beam is adjusted in a lateral direction to suit individual circumstances, the spindle f sliding back and forth in the block g.

Near one end of the pen-beam e is connected a beam, z, by a binding-screw, a. This beam is provided with an adjustable weight, b, having a set-screw, 0, whereby the supplemental arm, to be presently described, for actuating the pen-beam, is counterbalanced, and whereby the degree of pressure of the pens upon the paper is regulated. An actuating-arm,d, is pivotally connected to the pen-beam e,near one end thereof, and this arm is provided with set-screws 6, whereby the angle of the army with respect to the pen-beam maybe adjusted so as to give the proper inclination to the pens. The foot of the arm d is provided with a steel contact-plate, f, beveled off on the under side, and made adjustable by a screwconnection, 9. This plate is engaged by the cam-blocks d as they pass under the same, the lifting of the plate serving to partially rotate the pen-beam e and lift the pens from the paper collectivelythat is to say, to lift all the pens simultaneously, As the cam-blocks pass from under the plate f the pens descend to the paper in a body and recommence ruling.

To the arm (Z is connected an interiorlyscrew-threaded block, h,through which passes a threaded adjusting'rod, t, the same having a head and jam-nut, j, whereby it is set in a fixed position. The lower end of this rod rests upon a plate, Z, extending from an adj ustable bracket, m, secured to one of the side pieces A. This screw serves to deter mine the pressure of the pens upon the paperthat is, it fixes a point beyond which the penbeam cannot oscillate-so that the pens are prevented from being pressed hard against the paper,while the weight bprevents them from leaving the paper. A lug, p, is pivotally connected to the bracket m, and serves to hold the pens above the paper by lifting the arm (1 by hand and slipping it under the lower end of the screw 2" while the operator is making any given adjustment.

The letter q indicates the pen-clamp, the same being provided with a tongue,which enters a groove in one edge of the pen-beam e, and is secured in place by, one or more set- IIS screws, 1'. A supplemental pen-clamp is provided, consisting of the ra-bbeted strip 8, secured to the beam 0, having a metallic strip, t, secured to it, and of the bar a. The bars 8 and u are kept in relative position by the pins w extending from the latter into the former. These bars are bound together by metallic clamps consisting of plates fitting at one end within the rabbet of the bar .9, and connected at the upper ends by a rod, :0, a set screw, y, and washer 2 being employed to bind the bars .9 and it together and to hold the extended shank of the long pen. This device is used when it is desired to rule lines of two or more colors, a pen with a long shank in such instance being held by said clamp and extended slightly beyond and between the two pens held by the clamp q, as seen in Fig. 1

As an auxiliary means of actuating the penbeam, we have provided a supplemental arm, 1, similar to the arm (2, as seen in Figs. 1 and 2, the said arm having at one end a plate adapted to be engaged by a cam, .to be presently described, and the other end being pivotally connected with a sliding plate, 2, setscrews3 and 4 being employed to adjust this arm for the same purpose as that ascribed to adjusting the arm (1. A slide, 5, is provided with an extension, 6, having ways 7, with which the slide2 engages. The slide 5 fits within ways 8, formed on a plate, 9, secured to the pcnbeain c, as more clearly seen in Fig. 1.

Referring back to the cam L, it should be observed that the same is provided with one offset in its periphery, as seen in Fig. 6,while the cam M is provided with two offsets at two diametrically-opposite points, as also seen in that figure.

A rock-shaft, 10, is journaled at one side of the machine in the plate Z, as seen in Fig. 1, and at the other side in abar, 11, connected with the other plate Z, as seen in Figs. 1 and 4. To this shalt, near one end, is fastened a short arm, 12, as also seen in Figs. 1 and 4, and is connected with one of the side pieces of the frame by a spring, 13, and rod 14, and binding-post 15, through which the rod passes. The downward movement of the arm 12 is limited by an india-rubber stop, 12, held in a socket, 13. By this means the tendency of the shaft is to rock in the direction of the arrow, seen in Figs. 4 and 6, which tends to normally lift the stop-gate, as will presently appear, from the apron. A trip, 16, is attached to the shaft 10, ,and consists, essentially, of a collar having a block, 17, pivotally connected thereto, and carrying a finger, 18, as further described in Letters Patent issued to Hickok, Cooper, and Brown, January 27, 1880. This finger presses against the one or the other of the cams L or M, according to adjustment, and resists the tendency of the spring 13 to rotate the rock-shaft 10. Several short arms, 19, are secured to the shaft 10, and are 0011- nected with the stop-gate 20, consisting of aba-r having downward] extending lugs which normally engage the upper surface of the apron H, these devices being more clearly repre-' sented in Fig. 7. Thus it will be observed that when an offset of the cams L or M passes upwardly by the finger 18 the same will immediately drop into the depressed portion of \Ve shall now refer to the mechanism which immediately operates the pen-lifters. A pinion, 21, is loosely mounted on the shaft J and rigidly connected with the cam M, whereby it receives rotary motion from the friction-disk K. ion, rigidly mounted on the shaft 23, having a bearing at one end in a bracket, 24, one end of which bracket is supported by a rigid connection with the end of the shaft J. The other end of the shaft 23 finds its support in the bracket 25, and on this shaft are mounted a convenient number of cam-heads, 26, having annular grooves which receive cam-blocks 27, secured therein by set-screws 28. A rod, 29, is also mounted in the brackets 24 and 25, as more clearly seen in Figs. 1 and 2. To this rod are rigidly connected collars 30, having lugs 31, as clearly seen in F ig. 8. Loosely mounted on the rod 29 are sleeves 32, on the upper surface of which are formed short plates 33, and to a lip, 34, extending from said plate is pivotally connected a pen'liftenactuating arm, 35. This arm is provided at one end with a contact-plate, 36, with which the camblocks 27 on the cam-heads 26 engage, where by the said arms are depressed. This arm is also provided with adjusting-screws 38, whereby its relative position with the plate 33 is adjusted so as to regulate the lifting and the position of the pen-lifters, as will presently appear.

Extending from the sleeves 32 are short legs 39, terminating in boxes 40, having openings extending through the same from side to side and from front to back. In the latter opening is fitted the pen-lifter 41, and in the former are fitted the rod 42 and the block 43, the latter resting upon the uppersurface of the penlifter, and a setscrew, 44, being employed to bind these several parts together. The lug 31 and the arm 35 have short studs 45 extending from them, over which is fitted an elastic band or other spring, 46, whereby the arm 35, plate 33, and lug 31 are yieldingly held together. Blocks 47, similar to blocks 40, though separate from the legs 39, are fitted to the rods 42 and provided with other pen-lifters, 48. It will be observed that an almost {indefinite The cam then passes on and This pinion meshes with a similar pin- IIO number of these latter blocks and their penlifters may be fitted upon the rod 4.2,whereby as many pens may be lifted by one cam-head as may be necessary for any particular design.

The pen-lifters consist, preferably, of metallic strips extended from the boxes out to and underneath the pens, and may be wide enough at the point to lift one or more pens.

It should be observed that as the collars 32 are mounted loosely onthe rod 29, the independent sets of pen-lifter arms 35 may be actuated at different times or synchronously by placing the cam-blocks 27 of the cam-heads 26 in line with each other, or in advance one of the other, so as to engage the plates 36 at different times or in succession. By this means an almost indefinite number of lines of different lengths may be ruled by simply adding additional cam-heads 26 and pen-lifter arms and their immediate devices.

The operation of our machine will be readilyunderstood when taken in connection with the foregoing, and is as follows: Let it be supposed that the paper to be ruled is to have three lines each nine inches long, two lines each eight and one-half inches long, and three lines each seven and seven-eighths inches long. The nine-inch lines being the longest, their length will be determined by the frequency of the raising of the pen-beam entire. In order, then, to produce lines nine inches long, the pointer U will be set opposite the graduation 18 on the scale D by actuating the hand-wheel Q. Then the trip 16, mounted on the shaft 10, is adjusted so that the finger thereof will engage the cam M, having the The first of these adjustments will give the disk Kvthe proper speed to cause the apron to travel nine inches, and consequently to move the paper nine inches under the pens, while half the cam M in rotating passes the finger 18, the stop-gate during this time being down,so as to prevent the passage of any incoming sheet until the proper time. When the depressed portion of the said cams periphery reaches the finger, it drops into the same, and thereby allows the spring 13 to lift the stop-gate and allow asucceeding sheet of paper to pass on to the pens. Should the first sheet have been longer than nine inches, then the succeeding sheet would have lapped over that part of the first sheet, yet not beyond the gate when the gate was raised. Thus the second sheet is allowed. to accompany the first, and is lapped over that portion of the first in excess of the nineinch line, which portion usually forms the head of the sheet. Thus, also, it appears that the pens will ride upon the second or succeeding sheet just as the lines on the previous sheet are completed, the sheet being fed in foot first.

From what has been said it will appear that the gate will be actuated or lifted twice at each revolution of the cam M. This is done in order to allow the sheets to succeed cording to the scale in the present case,) the trip on shaft 10 will be placed so as to engage the cam L, which has but one offset, which will be found to allow the spring 13 to actuate the gate with sufficient frequency for lines of that length. The double cam maybe used, however, in such latter instance; but the pointer in ruling a line twelve inches, if the double cam is used, would be set opposite the graduation 24 on the scale.

The following is the rule governing the use of this portion of the macnine: In ruling lines from six to twelve inches, exclusive of twelve inches, the double cam is used, and the pointer set onzthe scale atdouble the number of inches to be ruled. In ruling lines between twelve inches and upward, inclusive of twelve, the double cam may be used, but the single cam is generally used. Now, to resume the example under consideration, a penlifter is adj ustedunder each of the pens which is to rule the line eight and one-half inches long, and the cam-blocks in either of the camheads 26 which is to actuate said lifters are adjusted by hand until they lift the lifters at the proper time to make a line of that length. Under each of the pens which are to rule the lines seven and seven-eighths of an inch long a pen-lifter is adjusted, and the cam-head which is to actuate them set in the manner above described. I

It is to be observed that when the ruling is to be done on the lapzsystem plan either of the alternative means hereinbefore describednamely, the cam-head on the .pencylinder shaft, or the cam-head on the shaft 23-is adjusted so as to lift the pen-beam and all the pens entire with it at the proper time to terminate the longest lines being ruled.

. When ruling as in the example above given, and the paper passes far enough under the pens to complete the shorter lines, they (the pens) are lifted by their lifters and heldup IIO until the paper passes far enough to complete the longer lines, when they again descend to work, the pen-beam entire not being elevated at all, the pens which rule the longer lines running from one sheet onto the foot of the succeeding sheet. When, however, the paper is fed foot first, but is not being lapped, then the same operation takes place as to the pens which are ruling the shorter lines, and, in addition to this, the pen-beam entire is actuated to raise the pens which rule the longer lines, when the paper has passed far enough to complete such lines, and all the pens are thus held from the paper while that part of the same which constitutes the heading is passing under the pens. They all descend again to the paper when the new sheet reaches them foot first. Again, when the paper is fed in head first and the heading-space is left, the pens entire remain elevated until the pa per reaches the point where the longer lines are to commence. WVhen this takes place, the pen-beam tilts and the pens come down to the paper, save those which are to rule the shorter lines, which are resisted by the pen -1ifters until the paper passes far enough to present the points of commencement of the shorter lines under the-pens. It will be understood that to do this either the cam-head on the pen-cylinder shaft or the cam-head on the shaft 23 is adjusted so as to hold the pen-beam up and let it down at the proper time.
